Semiconductor Ceramics Description

Advanced ceramics are a critical part of semiconductor manufacturing equipment.A large amount of plasma is generated during the semiconductor manufacturing process, and it is crucial to use plasma-resistant materials as equipment components. Compared with metals, resins, and glass, advanced ceramics are more high-performance and reliable. Their resistivity is usually between conductors and insulators, and their electrical insulation is excellent, making them very suitable for semiconductor manufacturing processes.

We provide you with all the ceramic materials you need:
Alumina (Al2O3) —Ultra-high purity and rigidity;
